Abstract

Copper or copper alloys are cleaned with an aqueous solution (pH at least 8) containing (% by weight) 5 to 15 of ammonium carbonate, 5 to 25 of ammonia and at least 0À1 of hydrogen peroxide. The copper may be subsequently washed, dried at 70 C., and then heated at 120 C. The ammonium carbonate may be formed by adding the acid carbonate to the solution.
